Re: DuplicateHandle(in) failed (e=6)

[Lynn Lin]

Thanks very much for your quick response.

I am not sure whether I describe this issue well. The third party call the perl 
script (this perl script call gmake) perl use pipe to capture gmake output .It 
report the above error

There is one piece code in makefile.
DDIRS = $( foreach dir,$(OBJLISTDIR),$(shell cmd.exe /C "md $(dir) 1>NUL 
2>NUL)))

%.bin:... $(DDIRS)
         command

If I remove 1>NUL and 2>NUL ,the error go away. But I continue see the error 
which haven't identified in which makefile code

Process_easy :  DuplicateHandle(In) failed (e=6)
processor_easy: failed to launch process failed (e=6)
